Genetic abnormalities begin to creep into a breed, owners decide they'd like to show off their breeding programs in the show ring, and breeding for show can lead to production of dogs that do well on exhibit but have lost the purpose for which they were developed.
«These results are exciting, because it means we could use an easily accessible blood test to help diagnose people who have the premutation
genetic abnormality and identify who is more likely to have problems and
begin early treatment,» said study author Kim M. Cornish, PhD, of Monash University in Victoria, Australia.
